You can't possibly be serious?
Not always. "Knowledge" can be used to refer to comprehension as well. In fact, it is rather common to hear someone to be speaking of something that he knows someone else has great comprehension of and say "you know it, don't you?".
Clearly, you failed to understand what i wrote. If someone "comprehense," doesn't it follow that there is something to have comprehension of? Well, if so, then what could one possibly have "comprehension" of-----if not of something that they must already have some cognition of? Well if so, then how do you term the relationship between a person who has no comprehension of something, and someone who does? What, that one of the 2 people knows something that the other does not? Ok, so what is knowing?
My primary claim still remains unshakened: Knowledge is the contents of ones knowing. Period.
Lets take a few analogies:
You are a teacher of a Kindergarden class. You teach simple things like the alphabet. From your teaching experiences, you know that some of your studants can actually recite their alphabet from A to Z. And you also know that some studants, can recite some of the alphabet, but not all the way to Z. Some child might actually in fact, be able to go as far as only the letter M.
Now, can we say that the child who can only go as far as M, is the same as the child who can go from A to Z without a problem?
From this perspective then, we can infer that there is a difference in having an idea of something, and being able to actually know something.
For the child that can demonstrate to the instructor their knowledge of the alphabet can clearly be justified in the receiving the charge, that "He knows his alphabet." But can we say the same thing to the child who can not go past the letter M, that "she knows the alphabet"?
Clearly, from this very simply analogy we can see that there's a difference between having the gist of something, and knowing something.
To have knowledge then, means to know what you could know. But what is the opposite of not having knowledge? Could be ignorance?
No it doesn't. "Knowing" refers to a filing away of information gathered from cognition. The state of cognition is called consciousness.
Now, you are just being silly.
If you are not cognising, does it mean that you have knowledge about something that you can't possibly have cognition of?
To cognise means to be aware of something. One could say that to be aware of something relates very closely to having knowledge of something, since you are having some kind of awareness about something.
